' sack-resumes- Specification of Letters Patent;

Application filed March 18, 1915. Serial No. 15,280.

To all whom, it may concern Be it known that I, CLARENCE L. CovnLL, a citizen of the United States, residing at Sykeston, in the county of Wells and State of North Dakota, have invented certainnew and useful Improvements in Sack-Fasteners; and I do'decla-re the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates broadly to improvements in devices for sealing containers, an specifically to an article designed for fastening the mouths of sacks in closed position.

The object of the invention is to provide a device of this class which may be very easily and inexpensivelymanufactured and marketed, yet which will be very efficient in operation. v

With this object in view, the invention resides in certain novel features of construction and combination hereinafter described and particularly pointed out in the appended claim.

In describing the invention, I shall refer to the accompanying drawing wherein like reference characters designate corresponding parts'throughout the various views and wherein:

Figure 1 is a side elevation of the sack showing the application of the invention to use. Fig. 2 is a perspective view of the fastener in open position. Fig. 3 is a vertical transverse section as seen along the plane indicated by the line 3-3 of Fig. 2. Fig. 4 is a top plan view of the fastener, partly in horizontal section, this view showing more particularly the action of a resilient tongue in retaining the latch member in open position. Fig. 5 is a similar view showing the action of this tongue when the latch member is closed thereby uniting the two ends of the I collar.

In this drawing, constituting a part of the as provided with a plurality of spaced openmgs 5 adapted to receive a latch member to be described.

As clearly shown in Figs. 2, 3 and 4, the folded portion of the band 1 is provided with a notch 6 into which a resilient tongue formedintegrally with the bandprojects. The tongue 7 contacts with the pivoted end 8 of a curved latch member 9 here shown in substantially the form of a tongue, it being evident from the drawing, that this member is disposedcontiguous to the outer side of the guard plate 4:, this being expedient in order that said membermay not mutilate a sack S when the invention is applied to use on the neck thereof as seen in Fig. 1.

By constructing the pivoted end of the member 9 as shown in the drawing, and by disposing said end for contact with the tongue 7 the latter will retain the former in either its inactive or active position as clearly shown in Figs. 4 and 5. Needless to say, the member 9 is first passed through one of the openings 5, before disposing it to its operative position, in which position it is not only held by the action of the tongue 7, but by a slide 10 which is shiftable upon the band 1 (see more particularly Figs. 1 and 5).

In addition to the features above described, the band 1 is preferably provided with a plurality of inwardly struck prongs 11 which prevent slipping thereof upon the sack. The guard plate 1 is also preferably provided with an opening 12 through which and through one of the openings 5, an appropriate type of seal 13 may be passed after the sack has been fastened as shown in Fig. 1. I

Although any preferred type of pivot could well be provided for the member 9, the upper and lower edges of the pivoted end thereof are preferably formed with small ears 14 which are rotatably disposed in sockets 15 formed by striking the adjacent portions of the folded end of the band outwardly in opposite directions (for this construction see more particularly Fig. 3.)

From the foregoing description, taken in connection with the accompanying illustration, it will be seen that avery simple and inexpensive device has been provided for carrying out the object of the invention, yet that the same will be very efficient in o eration and will possess a number of a vantageous features.

' "res raann'r ornrc. V

I claim: 8 A sack fastener comprising a strip of resilient metal having its ends brought to 1 gether to form a collar, one of said ends havfolded rearwardly upon its inner side and 'ing therein an opening to receive a locking tongue, the other end of said strip being then bent forwardly and extended into overlapping relation with the first named end, the rearwardly folded'portionof said strip being formed with a notch opening through the fold proper, and the part of said strip contacting withsaid folded portion being formed with two vertically spaced'elon- 'gated notches also opening through the aforesaid fold proper,

whereby to leave a resilient tongue between said two notches, a

hook-shaped locking tongue having one end Copies of this patent may be obtained for five cents each, by addressing the disposed in the first tact with the resilient tongue, to allow the latter to hold the former in its adjusted position, and a pair of pivot studs formed integrally with said locking tongue and received between the aforesaid rearwardlv folded portion of the strip and the aforesaid "Commissioner 01' Patents,
